Apache Error HTTPD: NoCase option for non-regex pattern is not supported and will be ignored.

Written by Sparko | 4 January 2010

An Apache error came to fill all our Apache error_logs.  We (programmers) tend to use the [NC] flag in the .htaccess files that we create so that Apache doesn't consider the case when using RewriteCond.

The error is:
 

[warn] RewriteCond: NoCase option for non-regex pattern '-f' is not supported and will be ignored.

[warn] RewriteCond: NoCase option for non-regex pattern '-d' is not supported and will be ignored.

 

So instead of using in .htaccess:
 

RewriteCond %{REQUEST_FILENAME} !-f [NC,OR]

RewriteCond %{REQUEST_FILENAME} !-d [NC]

prefer to use:
 

RewriteCond %{REQUEST_FILENAME} !-f [OR]

RewriteCond %{REQUEST_FILENAME} !-d

 

Another (yet better!) solution is to use:
 

RewriteCond %{REQUEST_FILENAME} -f

RewriteRule "." - [skip=100]

RewriteCond %{REQUEST_FILENAME} -d

RewriteRule "." - [skip=100]
